Even in the face of an endless torrent of free and subscription music services that are doing their best to effectively soak up the world's 3G bandwidth, carriers are showing no sign of giving up the fight for a piece of the audio download revenue pie; indeed, three of the four US nationals run their own branded (or co-branded) services. Sprint happens to be in that group, and they're looking to present a slightly more unified front by bringing tracks, ringtones, and ringback tones under a single roof that'll be managed by RealNetworks' Media Entertainment Platform. The result should be a "streamlined" user experience (read: it'll be more compelling to spend a dollar here, a dollar there as you browse through Sprint's mobile portal) when the new services launch later this year, but no specific date's been set as of yet.
